Using 3 Dimension Health Vegetation Index Point Clouds To Determine Hlb Infected Citrus Trees, Joseph Cerreta, Ashley Hanson, Julianna E. Martorella, Stacy Martorella
Journal of Aviation/Aerospace Education & Research
Three-dimensional NDVI point clouds can be an innovative method for detecting Huanglongbing (HLB) disease in citrus trees. In February 2018, an Unmanned Aircraft System (UAS) captured narrow-band multispectral images to detect healthiness variations of infected citrus trees. A 30-acre section of a citrus grove in Florida with a known HLB infection was examined to determine if three-dimensional Normalized Difference Vegetation Index (NDVI) point clouds can indicate healthiness variations in HLB-infected citrus trees and how three-dimensional NDVI point clouds compared to two-dimensional NDVI reflectance maps for detecting healthiness variations in HLB-infected citrus trees. Wilcoxon Sign Rank testing compared Whole-Tree Vegetation Indices …

Assessing Computer Vision Syndrome Risk For Pilots, Curt Mowry, David C. Ison
Journal of Aviation/Aerospace Education & Research
The purpose of this study was to determine if pilots are at risk for computer vision syndrome (CVS) as computer display technology becomes commonplace in modern cockpits and simulators. A review of computer vision syndrome respect to causes and effects is provided. Display technology used in aircraft and simulators are outlined. Ergonomics and human factors for pilots in aircraft and in simulators are discussed in relation to video displays. A survey of 178 individuals was conducted to determine if there is a statistically significant link between exposure to computer displays and three categories of symptoms of CVS on the flight …
